摘　　要：利用废弃聚酯的降解产物制备聚氨酯泡沫,优化了聚氨酯泡沫的制备工艺.其中,最佳工艺为：降解产物为10份,催化剂j的用量为1.0～1.1份,水的用量为1.0～1.1份,异氰酸酯的用量为20份.该工艺条件下得到的泡沫密度小、压缩强度高、热性能稳定.工艺优化后聚氨酯泡沫的密度为62 kg/m3,压缩强度为400～420 kPa,初始热分解温度为250～260℃.Polyurethane foam was prepared by degradation products with recycled PET,and the process of the polyurethane foam was optimized.The optimal process is degradation product 10 parts,catalyst amount 1.0 to 1.1 parts,amount of water 0.8 to 0.9 parts,amount of isocyanate 20 parts,with which the foam has low density,high compressive strength,thermal stability.After the process optimization,polyurethane foam density is 62 kg/m3,the compression strength is 400-420 kPa,initial thermal decomposition temperature is 250-260 ℃.
